To all whom it may concern.-

Be it known that I, HEINRICH WINTER- WERBER, ofOtfenbach-on-the-Main,Germany, have invented certain new and usefulImprovements in Drying-Machines, of which the followingisafull,clear,and exact description, and will enable those skilled inthe art to which these improvements relate to make and use the same,reference being had to the accompanying drawings.

This invention belongs to that class of drying-machines in which thepaper or other material to be dried is carried in folds upon loosesticks resting upon a conveyer consisting oftwo parallel bands orchains, the apparatus being arranged to receive the paper while in itsdamp state, and to can se it to dry by carrying it slowly to thewindingmachine or other means for collecting it, the paper during itspassage hanging in long folds or loops from the sticks on theendless-band conveyer. In connection with this conveyer an apparatus isnecessary at the receiving end of the conveyer for placing the sticksfrom which the paper hangs under the paper and upon the conveyer, and insuch manner that the loops in the paper will be uniformly and properlyformed. So, too, a device is required at the delivery end of theconveyer that will receive the sticks when the paper leaves the conveyerand return them to the apparatus that places them under the paper; andthe first feature of invention consists in improved devices for thushandling the said sticks. I

It is often found necessary to employ a conveyer of greater length thanis convenient to the room or space in which the drying process iscarried on, if the conveyer were all in one length or span, and in suchcase it is usual to arrange the conveyer so that it doubles on itself,or is in two or more spans, thus in the case of two spans, or where theconveyer turns back once, bringing the delivery end thereof opposite thereceiving end, this latter arrangement also making it convenient for thestickreceiving machine to be close to the stick-placing machine. Inmachines where the conveyer thus deviates from a straight course itbecomes requisite to provide means other than or inconjunction with theconveyer for carry.- ing the sticks around the corner or angle where theconveyer turns, for in turning this corner or angle it is obvious thatthe inner ends of the sticks must be moved more slowly than their outerends, which the parallel bands or chains of the conveyer running at thesame speed cannot do; and the second feature of invention consists of animproved device for thus carrying the sticks around the turn where theconveyer changes from its straight course.

In the drawings, Figure 1 is a side view of the receiving end of amachine embodying my improvements. Fig. 2 is a plan view of the same.Fig. 3 is a side view of the delivery end. Fig. 4 is an end view fromthe right. Figs. 5, 6, 7, and 8 are detail views of the turningmechanism. Figs. 9, l0, and ll are views of a modified form.

In these views, A represents the paper or other fabric or material to bedried. B is the paper-conveyer, consisting of two chains runningparallel to each other at the same speed and near to or on suitabletracks or guides,O.

D indicates the sticks, which lie upon the conveyer, and from which thepaper hangs in loops, as shown. This conveyer is supported on suitablepulleys on hangers or like devices at a proper height from the floor toprevent the paper touching the floor, and to permit the forming of aslong loops in the paperas is practicable.

E is an endless belt extending from the receiving end of the conveyerdown to the open bottom of the stick-holder F. This band is providedwith, lugs or hooks G, of such length as to catch the bottom stick inthe holder and carry it up to the conveyer B, the paper being caught upon the stick as shown, and the belt E traveling enough faster than theconveyer to bring the loops of paper as near each other as ispracticable without their damp surfaces rubbing together. WVhen thedelivery end of the conveyer is reached, the sticks (with the now drypaper upon them) run upon the inclines H, which rise up a little fromthe conveyer and guide-rail, and thus cause the sticks to be collectedclosely together, as shown. This is to insure there always beingsufficient paper at the delivery end of the machine to prevent thewindingrolls, upon which the paper runs'from this delivery end,fromtaking the paper faster than the conveyer can deliver it. So, too, whenit becomes necessary to stop the windingrolls, or when for other reasonit is desired to stop the delivery end of the paper for a short time,this may be done without stopping the conveyer, as the sticks and foldsof paper will go on collecting on these inclines until they are full. Asthe paper is drawn from the conveyer, the sticks are pulled over the endof the inclines and drop upon theendless belt I, which, moving fasterthan the conveyer, and being provided with lugs or hooks J, takes thesticks quickly from under the paper and carries them to the receiver K.At one end of this receiver is a starter, L, which is driven by thecrank M and connecting'rod N. As the sticks are deposited in thereceiver, this starter pushes them in between the yielding grip-rolls O,and these rolls shove them into the holder F at the delivery end of theconveyer, from which they are again taken and placed upon the conveyer,as before. Should this stick-holder become filled, its top being leftopen, the sticks pass out of it and into anysuitable receptacle placedto receive them.

1? represents the wheel around which the inner chain of the conveyerruns where the conveyer changes its direction. This wheel isprovidedwith a flange or disk, Q, projecting over the chain and arrangedjust above but not touching the ends of the sticks as they lie upon bothchains of the conveyer. At the point where the sticks should begin toturn around to the parallel span of the conveyer the outer chain isconducted downward and comes up to the outer side of the next span, sothat the outer ends of the sticks are at this point left free and dropslightly, as shown, being held by their inner ends only, which bear uponthe inner chain and on the under face of the disk Q. In this positionthe sticks are swung around till nearly in apositiou at right angleswith the second span of the conveyer, where their outer ends are lifted(thus freeing their inner ends from the flange-disk,) and placed uponthe outer chain again by the notched wheel R, which is driven by theouter I chain running over pinion S on the same shaft therewith, and isso arranged that its periphery moves with the same speed as theperiphery of the inner chain-wheel, P. This causes the outer ends of thesticks to be again laid upon the outer chain of the conveyer in the samerelative positions as before.

A wheel acting in all respects like wheel R, but in reverse, may be usedto let the outer ends of the sticks down gradually,where they arereleased from the outer chain, and this I show in other figures.

In Fig. 9 I show the chains composing the conveyer arranged entirelyabove the floor, Fig. 10 being a cross-section in w a; of Fig. 9, andFig. 11 being an end view of the same from the left.

Here the outside chain starts from one of its driving-pulleys, T, runsto the turningpoint, where it operates a notched wheel, U, for lettingthe outer ends of the sticks down easily, as already described; thenturns back over pulley V and guide W, and over to a correspondingnotched wheel, X, for taking up the outer ends of the sticks; then toanother driving-pulley, Y, upon which it is held by a friction-wheel, Z;then, making aloop, it passes over guide A, and, forming another looparound slip-pulley B, it returns to the first driving-pulley,T. The twodriving-pulleys T and Y are connected by the shaft D, and the slack orloops in this outside chain are to insure it being taut where it iscarrying the sticks and paper, and yet slack between the twodriving-points and around as many angles as possible to prevent binding.The inside chain is driven from shaft D by pulley E, which also has afriction-wheel like the other driving-pulleys, from which it loops overto pulley F, from there it runs to the chain-wheel G, and then back toits drivingpulley. The pulleys H are those upon which run the belts fortaking the sticks to the conveyer, and the pulleys I are those thatcarry the upper ends of the stick-delivering belts. By this arrangementthe whole conveyer part of the drying apparatus may be suspended fromthe ceiling of the room, thus making a more compact apparatus for asmall space.

Vhat is claimed as new is- 1. In the herein-described drying-machine,the combination of the conveyer for carrying the paper hung in loopsfrom sticks thereon, the stick-receiving belt with its stick-holder, andthe stick-delivering belt with its receiver and stick-starter, and thegrip-rolls for shoving the sticks into the holder at the receiving endof the conveyer, substantially as set forth.

'2. The combination, in a drying-machine in which loose sticks are usedto suspend the material being dried, a belt for delivering the sticksinto a receiver, rolls -for withdrawing the sticks from the receiver andtransferring them to a holder, and a starting device for pushing thesticks between the rolls, and a belt for taking the sticks from theholder and placing them in position for use, substantially as described.

3. In a dryingmachine consisting of a con veyer for the material to bedried, composed of two parallel endless bands or chains, a turningmechanism for taking the sticks around a curve or angle where theconveyer deviates from a straight course, consisting of a wheel forcarrying the inner chain,'which is provided with a flange or diskarranged above and for the inner ends of the sticks to bear upon,substantially as and for the purpose set forth.

4. In combination with the two chains or bands of the conveyer, thewheel P, provided with the flange or disk Q, and the notched wheel R,for lifting the outer ends of the sticks and placing them upon the outerchain, substantially as set forth.
